Question

the area of rectangle is 540 CM square and its length is 36 cm find its with and perimeter

Answer 1

Heya friend!!
Rajdee here!!

Area (a) is 540 cm^2
Length(l) is 36 cm

WE know, a = l x b
so b = a/l
=> b = 540/36
=> b = 15 cm

Perimeter is 2(l + b)
= 2(36 + 15)
= 2 x 51
= 101 cm

So the width is 15 cm and the perimeter is 101 cm.

Thanks!!

Answer 2

breadth= area divided by length
=540cm ÷ 36 cm
=15 cm
perimeter =2 x l + b
=2x 36 cm +15 cm
=2x 51
=102 cm
