Question

Find the length and perimeter of the rectangles. (a)- Area = 42 sq cm ; Breadth = 6 cm. please solve and tell ​

Answer 1

let length of rectangle is x

Breadth=6cm

Area = l x b= 42

x × 6= 42

x = 42/6

x = 7

perimeter=2(l + b)

2(7+6)

2 (13)

= 26cm

So, perimeter=26cm

length = x=7cm
