Answer 1

Q2.

625=20x + 25

625-25 = 20x

600 = 20x

600/20 = x

60/2 = x

x = 30

x= 30

Q3.

L= 35m

Area= 525m²

b= a

A= lxb

= 35xa

= 35a

525= 35a

525/35 = a

a = 15

Verification*-

A= lxb

= 35x15

= 525m²

Answer 2

Answer:

2. The value of x is 30

3. The breadth of rectangle is 15m

Step-by-step explanation:

Questions:-

2) Find the value of x: 625 = 20x + 25

3) If the length of a rectangle is 35m and its area is 525m ^ 2 . Then find its breadth.

Solution:-

2. 625=20x+25

$\mapsto \: 625 - 25 = 20x$

$\mapsto \: 600 = 20x$

$\mapsto \: \frac{600}{20} = x$

$30 = x$

Value if x is 30

3.Length of rectangle=35m

Breadth of rectangle=?

Area of rectangle=525m^2

As we know,

Area of rectangle=length×brradth

$525 {m}^{2} = 35m \times b$

We already know the area so we are substituting the value in this

On substituting the given values we get,

$\mapsto \: \frac{525 {m}^{2} }{35m} = b$

$15m = b$

Therefore the breadth of rectangle is 15m
