Answer:
fff
Step-by-step explanation:
fff
If you know the base and area of the triangle, you can divide the base by 2, then divide that by the area to find the height
Step 1. 14 ÷ 2 = 7
Step 2. 45.5 ÷ 7 = 6.5
Height = 6.5 cm
W = L - 15
WL = 76
(L-15)L = 76
L^2 - 15L - 76 = 0
(L-19)(L+4) = 0
L = 19 or -4
Since a length cannot be negative, the length must be 19 units.
The width is 19-15=4 units.
