Q

Step-by-step explanation:

The nearest perfect square of sqrt10 is sqrt9 and sqrt 16, representing a 3 and 4.

A triangle has an area of 35 square inches. the length of one of the sides it 10 inches. what is the length of the perimeter? in
Serggg [28]
The perimeter would be about 34.4 because if you choose the bottom side to be ten, by multiplying 35 by 2 to get 70 you can divide by 10 to get 7. Since you know the height and width, you can use pythagorean theorem, a^2 + b^2 = c^2. Plug in the numbers you have 10^2+7^2=c^2. c^2=149, so if you square root 149 you will get a irrational number but when rounded you get 12.2- so that is one side multiply by 2 and get 24.4- and add 10 to get 34.4
