Number of unit squares = 23
Now, 1 = 1 sq. unit
Area of figure = 23 square units
Now, 1 = 1 sq. unit
Area of figure = 23 square units

Perimeter of one square = 8 cm
Side of square = 8/4 = 2 cm
Perimeter of given shape = 18 × 2 = 36cm.
Side of square = 8/4 = 2 cm
Perimeter of given shape = 18 × 2 = 36cm.

Abhay Datta answered |
Perimeter = 160 cm
Breadth = 30 cm
2(Length + Breadth) = 160 cm
2(Length + 30 cm) = 160 cm
=> Length +30 cm= 80 cm
=> Length = (80 - 30) cm = 50 cm
Breadth = 30 cm
2(Length + Breadth) = 160 cm2(Length + 30 cm) = 160 cm
=> Length +30 cm= 80 cm
=> Length = (80 - 30) cm = 50 cm

We have,
BC = AL + KJ + IH + GF + ED
= (2 + 2 + 2 + 2 + 2)cm = 10 cm
Perimeter of the given figure
= (7 +10+7 + 2 +5+ 2 +5+ 2 +5+ 2 +5+ 2)cm 54cm
BC = AL + KJ + IH + GF + ED
= (2 + 2 + 2 + 2 + 2)cm = 10 cm
Perimeter of the given figure= (7 +10+7 + 2 +5+ 2 +5+ 2 +5+ 2 +5+ 2)cm 54cm
