I don’t understand how to find the dimension,<br> Need help :c
slava [35]

Width = W

Length = 2 times the width plus 3 feet = 2W + 3

Area of triangle A = L * W

A = W (2W + 3)

20 = 2W^2 + 3W

2W^2 + 3W - 20 = 0

(W + 4) (2W - 5) = 0

W + 4 = 0; W = - 4 (width cannot be negative, excluded)

2W - 5 = 0

2W = 5

W = 2.5

L = 2W + 3 = 2(2.5) + 3 = 8

Answer:

Width = 2.5 feet and Length = 8 feet

Hope it helps.

A circle has diameter 11cm
pogonyaev
In this case, to prove what is required, we must use the Pythagorean theorem to find the diagonal of the square.
 If the diagonal of the square is smaller than the diameter of the circle, then the square will fit perfectly in the circle without touching it.
 Diagonal = Root ((7 ^ 2) + (7 ^ 2)) = 9.89 cm.
 we observed that
 9.89cm <11cm.
 Therefore we show that:
 the square will fit inside the circle without touching the edge of the circle
