width= 7m
Step-by-step explanation:
Area= L×W
L= (x+8)m
W=8m
105m²= (x+8)m × (x)m
105m²= x² + 8x
-x² - 8x + 105= 0
(x-7) (x+15) = 0
x= 7 x= -15
x=width = 7m
Answer:
B :point 2 and point 3
Step-by-step explanation:
The only interior angles are 6, 2, 3, and 7
The angles equal to each other are 6 and 7 or 2 and 3

Answer:
90 cm
Step-by-step explanation:
15 x 6 = 90
Answer:
152 in. squared
Step-by-step explanation:
Surface area = L×W + L×W+ 1/2 ×h ×b+ 1/2 × b×h + L×W
= 7×6 + 6×5+ 1/2×4×8 +1/2×4×8 +6×8
= 42+ 30 +16 +16 +48
=152 in. squared
