Question

The length of a rectangle is 15cm more than its width.if the primeter is 150,find the dimensions of the rectangle

Answer 1

Answer:

30 and 45.

Step-by-step explanation:

2[x+x+15]=150

2x+15=75

2x=60

x=30

so first side =30

and second side =30+15=45

Answer 2

Answer:

Let the width of the rectangle be x

Perimeter =150

ATQ

2(x+(x+15)) =150

x+(x+15) = 150÷ 2

= 75

2x +15 = 75

2x = 75 - 15

= 60

x = 60 ÷ 2

= 30

width of the rectangle = x = 30

length of the rectangle =x + 15 = 30 + 15

= 45
