Question

find the length and perimeter of the rectangle whose area is 120 CM square and breadth is 8 cm

Answer 1

Answer:

area = 120cm square

breadth = 8cm

120 = length * 8

length = 120/8

length = 15cm

perimeter = 2(l +b)

2(15 + 8) = 2*23 = 46cm

Step-by-step explanation:

Answer 2

The length and perimeter of the rectangle are 15 cm and 46 cm respectively.

Step-by-step explanation:

Area of rectangle = $Length \times Breadth$

Breadth of rectangle = 8 cm

Area of rectangle =$Length \times 8$

We are given that area of rectangle is 120 sq.cm.

So, $Length \times 8 =120$

$Length = \frac{120}{8}$

Length = 15 cm

Perimeter of rectangle = 2(l+b)=2(15+8)= 46 cm

Hence The length and perimeter of the rectangle are 15 cm and 46 cm respectively.
