Area of triangle = 1/2 (b*h)
= 1/2 (13*5)
= 65/2
= 32.5 cm^{2}

Find the perimeter of the figure shown in the below
A square has an area of 64 cm^{2}. What is the length of each side?
The figure below is made up of 3 squares of sides 5 cm. What is the perimeter of the figure?
The figure below is made up of three squares. Find the perimeter of the figure.
The area of the figure above is _____
m^{2}.
The perimeter of a square is 20 cm. What is the length of each side of the square?
Which of the following figures have the same area?
Which one of the following rectangles had the biggest perimeter?
A) Area = 96m^{2}
Breadth = 8m
Area = l*b
96 = l*8
l =12
Perimeter = 2(l+b)
= 2(12+8) = 40
B) Area = 110m^{2}
Breadth = 10cm = 0.1m
Area = l*b
110 = l*0.1
l =1100
Perimeter = 2(l+b)
= 2(1100+0.1) = 2200.2
C) Area = 90m^{2}
Length = 15cm = 0.15m
Area = l*b
90 = 0.15*b
b = 600m
Perimeter = 2(l+b)
= 2(0.15+600) = 1200.3
D) Area = 100m^{2}
Length = 25cm = 0.25m
Area = l*b
100 = 0.25*b
b = 400m
Perimeter = 2(l+b)
= 2(0.25+400) = 800.5
The perimeter of the figure shown below is 36 m. What is the length of DE?
What is the area of the figure given below?
A rectangular garden measures 25 m by 20 m. What is the cost of erecting a wooden fence around it if every 5 metres of wooden fencing cost $ 27?
Let's take perimeter of recatngular garden=
2(20m+25m)= 90m
Cost of fencing every 5 m= Rs 27
Cost of fencing 90 m= $ 27/5 ×90
= $ 27× 18= $ 486
