Question

Rectangle is 5 times the width the peremeter is 120 find its area

Answer 1

Answer:

Area=275cm²

Step-by-step explanation:

length=5cm

let W represent width

Perimeter=2(L+W)

120 =2(5+W)

120 =10+2W

Group like terms

120-10=2W

110=2W

Divide both side by the co-efficient of W which is 2

110/2=2W/2

55 =W

therefore width=55cm

Since we have got the length and the width we can find the area

Area of a rectangle=length×width

=5cm×55cm

=275cm²
