Question

() Perimeter = 7.6 m and breadth = 75 cm find the length​

Answer 1

Answer:

29.9 cm

Step-by-step explanation:

Perimeter = 2 (l+b) = 2l + 2b = 75 cm

l = x

b = 7.6 cm

=> 2x + 2*7.6 = 75

=> 2x + 15.2 = 75

=> 2x = 59.8

=> x = 59.8/2

=> x = 29.9 cm

x = l = 29.9 cm

Answer 2

Given

Perimeter = 7.6 m

breadth = 75 cm

To find

We have to fine length.

Solution

Perimeter = 2 (length + breath) = 2 length + 2 breath = 75cm

Let us take length as x

Breath = 75cm

Now,

➥2 ( x + 75 ) = 7.6

➥ 2x + 150 = 7.6

➥2x = 7.6 - 150 = 142.4

➥ 2x = 142.4

➥ x = 142.4/2

➥x = 71.2

Therefore, the length = 71.2
