Question

the perimeter of rectangle CT 100 cm if the length is 35 cm find its breadth also find the area​

Answer 1

Step-by-step explanation:

$lb = 35 \times x \\ 100 = 35 \times \: x \\ 100 \div 35 = x \\ 50 \div 7 = x \\ x = 7.14285cm$

Answer 2

Given :-

Perimeter = 100 cm

Length = 35 cm

To Find :-

Area

Solution :-

We know that

Perimeter = 2(l + b)

Let the breadth be b

100 = 2(35 + b)

100 = 70 + 2b

100 - 70 = 2b

30 = 2b

30/2 = b

15 = b

Now,

Area = l × b

Area = 35 × 15

Area = 525 cm²
