Question

the area of rectangular field is 120 square metre if the length is 15 M find the breadth and the perimeter of the rectangle
question no . 8,9,10

Answer 1

Okay let me solve the 9 the one!

let's find the area of the wall = 4 m × 3m = 400cm × 300 cm = 12000cm^2.

Now find the area of the marbel tile = 25 × 20 = 500

Now divided the first one by the second one = 12000/500 = 24 answer.e

Answer 2

✬ Perimeter = 46 m ✬

Step-by-step explanation:

Given:

• Area of rectangular field is 120 m².
• Meaure of length of field is 15 m.

To Find:

• What is the meaure of breadth and perimeter of field?

Solution: Let the breadth of field be b m.

As we know that

★ Ar. of Rectangle = Length • Breadth ★

A/q

• Area is 120 m².

$\implies{\rm }$ 120 = 15 $\times$ b

$\implies{\rm }$ 120 = 15b

$\implies{\rm }$ 120/15 = b

$\implies{\rm }$ 8 = b

So,

➩ Meaure of breadth of field is b = 8 m.

Now, Finding perimeter of field

★ Perimeter = 2(Length + Breadth) ★

$\implies{\rm }$ Perimeter = 2(15 + 8)

$\implies{\rm }$ Perimeter = 2(23)

$\implies{\rm }$ Perimeter = 46 m

Hence, the perimeter of rectangular field is 46 m.
