What is the area of rectangle if Length = 2m, Breadth = 5m
The area of rectangle is given by length × breadth. So the area is 2 × 5 = 10m^{2}.
The third side of the triangle if the perimeter of a triangle is 20m and two of its sides are 5m and 4m, is
Perimeter of a triangle =1^{st}side+2^{nd}side+3^{rd }side So, 20=5+4+3^{rd}side 3^{rd}side=20−9=11m.
Calculate no. of shaded boxes. It comes out to be 21. And each box has area of 1m^{2}. So the area of shaded region becomes21m^{2}.
The difference between the length and the breadth of a rectangle is 8 cm and the perimeter is 64 cm. Which of the following can be the length and breadth of this rectangle?
Length of rectangle = x cm Breadth of rectangle = (x  8) cm Perimeter of rectangle = 2(x + x  8) = 2(2x  8) Given 2(2x  8) = 64 ⇒ 2x = 40 ⇒ x = 20 L = 20, B = 20  8 = 12
The area of a square is 100 sq. cm. If the sides this square are increased by 10% then what will be the area of new square?
Given area of square = 100 side×side=100=10×10 ⇒Side = 10 cm Increased in side of square = 10% of 10 = 1 ∴ New side = 10 + 1 = 11 ∴ Area of new square =(11)^{2}=121sq.cm.
The area of a square is equal to the area of a rectangle of I = 8 cm and b = 2 cm. What is the side of the square?
Area of rectangle = l×b
l = 8cm,. b= 2 cm
Area of rectangle= ( 8×2)cm
= 16cm^2
Area of rectangle= Area of square
therefore area of the square is 16cm^2
Area of square= (a)^2
√16 = a
Side of the square 4cm
A cuboid measures 24m × 12m × 10m. how many cubes of side 3m can fit in the box?
Given : length = 24 m , breadth= 12 m , height = 10 m
edge of a cube = 3 m
to find how many cubes of side 3 m can fit in the cuboid, let us first find the volume of the cuboid:
volume of the cuboid = l × b × h ⇒ 24×12×10 = 2880 m³
now, volume of cube :
vol of cube = a³ (where 'a' is the side ) ⇒ 3³ = 27 m³
no. of cubes that can fit in the cuboid = volume of the cuboid ÷ volume of the cube
⇒ 2880 ÷ 27 = 106.66 ⇒ 106 cubes
Calculate the area of rectangle given below if each square has an area of 4m^{2}.
There are 2×5=10 squares and each square has an area of 4m^{2} So, the area of rectangle =2×5×4=40m^{2}.
Area of rectangle is 32m^{2}. If the length is 8m then breadth = ________
Given, area = length × breadth⇒ breadth = area÷length So, the breadth = 32/8 = 4m.
If a figure has sides 4m, 2m, 4m and 2m then which type of figure is this?
There are four sides .So it cannot be circle or triangle. Now, it has 2 pairs of equal sides. So it is a rectangle as the square has all its four sides equal.
