Question

If a rectangle has the ratio of its length to breadth is 5:3 and perimeter is 64 cm, find the area.​

Answer 1

Answer:

Answer = 240 cm^2

Step-by-step explanation:

Let length be 5x

Let breadth be 3x

Perimeter = 64cm

64 = 2(5x + 3x)

64 = 2(8x)

64 = 16x

x = 4

Length = 4*5 = 20 cm

Breadth = 4*3 = 12 cm

Area = l*b

= 20*12

= 240 cm^2

Hope it helped :)

Answer 2

please mark me brainliest

Answer:

240squaremetres

Step-by-step explanation:

2(5x+3x)=64

8x=32

x=4

length=20

breadth=12

$area \: of \: rectangle = l \times b = 20 \times 12 = 240 {cm}^{2}$
