Question

The width of the rectangle is 2/3 of its length.if the perimeter of the rectangle is 80cm.find it's area.​

Answer 1

Answer:

the are is 384

Step-by-step explanation:

u have to take out the length 1st with the help of the perimeter

Answer 2

width = 2/3 length

•°• b = 2/3 × l

paremeter = 2(l + b)

80 = 2(l + 2l/3)

80 = 2( (3l + 2l)/3)

80 = 2 (5l/3)

80 = 10l/3

10l = 80 × 3 = 240

l = 240/10 = 24

now, b = 2/3 × l = 2/3 × 24 = 16

b = 16

• Area of rectangle = l × b

• => = 24 × 16 = 324sq unit

Area of rectangle is 324 unit²
