Answer:

The length of three sides are 28 in, 84in and 38in respectively.

Step-by-step explanation:

Perimeter = 150 inches

Let's assume first side as x. Then,

first side = x

second side = 3x

third side = 10 + x

Solution :

Perimeter = first side + second side + third side

150 = x + 3x + 10 + x

150 = 5x + 10

5x = 150 - 10

5x = 140

x = 140 / 5

x = 28

Now, length of each side:

First side = x = 28 inches

Second side = 3x = 84 inches

Third side = 10 + x = 38 inches
