Q.4 Find the perimeter of rectangles with dimension given below.
(a) length - 1.5m breadth 70cm​

Answer 1

Answer:

perimeter=length × breath

length = 1.5 m = 1.5 × 100 cm

= 150 cm

breadth= 70 cm

perimeter = 70× 150 = 10500 cm^2

Answer 2

Perimeter=2(L+B)

=>P=2(1.5+70)

=>P=2×71.5

=>P= 143.0

Therefore, perimeter of rectangle is 143 cm
