Answer:
this is ,y answer :)
Area = 46.83 cm²
details
The perimeter (P) is 36 cm.
Let L = length and W = width
P = 2L + 2W
L +W = 18 cm
Tan 78° = L/W
L = (Tan 78°)W = 4.705W
4.705W + W = 18
W = 3.155 cm
L = 18 - 3.155 = 14.844 cm
Area = L(W) = (14.844)(3.155) = 46.83 cm²:)
Step-by-step explanation:
Substitute the values of Area in the formula 'A = l × w' and simplify to find width 'w' in the form of length 'l'.
