Question

a rectangles side lengths are 8 cm and 4 cm. Approximate the length of the diagonal of the rectangle to the nearest tenth.

Answer 1

8.4cm

Explanation:

first you have to square both sides

8²+4²= Hypotenuse (the diagonal)

you'll get

56 + 16

next you add it, and it'll equal 72

lastly you'll find the square root of that number

which is going to give you 8.4
