Question

The perimeter of a rectangle is 150cm.the length is 15cm greater than the width. Find the dimension

Answer 1

Step-by-step explanation:

P= 150cm

let b = x

l= 15+x cm

we know P= 2(l+b)

150= 2( 15+x+x)

75= 15+2x

60= 2x = 30

b= 30cm

l= 45cm

Answer 2

Answer:

Perimeter of the rectangle =150cm

Let the width be x

And length =15+x

ATQ

2{x+(15+x)}=150 (Perimeter =sum of all side)

(x+15+x)=150/2

2x+15=75

2x=75-15

X=60/2

X=30

Therefore, width =x=30cm

And length =15+x=15+30=45cm
