Question

the length ofa rectangle is 15 more than the breadth.its perimeter is 150cm find out the length and breadth​

Answer 1

Step-by-step explanation:

Let The Length = x + 15

breadth = x

Perimeter = 150

now solve by putting values

perimeter = 2( l + b )

150 = 2 (x+15 + x )

150= 2 (15+ 2x )

150 = 2 *15 + 2 *2x

150 = 30+4x

150-30 = 4x

120= 4x

x = 120 /4

x =30

Length = x +15 =30+15=45

Check

150=2(45+30)

150=2 *75

150= 150
