Answer:
To solve this we calcuclate the total are then we subtract the 4 rectangles area
total area = length × width =10.5 × 10.5 = 110.25 cm²
the rectangles drawn accurately = 2(.5 × 7)
7 cm²
the rectangles drawn not accurately 2(.5 × 10.5)
= 10.5 cm²
so the shaded area = 110.25 - 7 - 10.5 = 92.75 cm²
Answer:
he height of a triangle is 8m less than the base. The area is 10cm^2. Find the height and the base.
I have tried the equation 10=b(b-8)(1/2).
b(b-8) = 20
b^2 - 8b - 20 = 0
Factor:
b^2-10b + 2b-20 = 0
90,000*.85 = $76,500 = Financing
