Question

the width of a rectangle is 7 cm less than its length. If it perimeter us 50cm calculate its dimensions​

Answer 1

Answer:length=10 width =5 Perimeter =30

Explanation:

Area =LxW

If area is 50cm^2 and length is 5cm more than The width then the length must be 10cm. Now divide the area by the length to get width. 50/10=5 which is the width.

The formula for perimeter is P=2L+2W

P=2(10)+2(5)

P=30
