It is 39..................................
Answer:
Yes she did
Step-by-step explanation:
There is .75 yards and she cut .1125 of it, it make it 15% as .75 x .15 = .1125
Answer: b₁ = 7 and b₂ = 14.
Triangle: base=21 cm, height=6cm
Trapezoid: height=6 cm, b1=?, b2=?
Triangle -> A=bh/2 -> A=63 (<em>b is base and h is height)</em>
Trapezoid -> A=[(b₁+b₂)/2)]h (<em>b₁ and b₂ are bases and h is height)</em>
Since they have the same area, the formula will be:
63=[(b₁+2(b₁))/2)]h
x=7
