The triangle and the trapezoid have the same area.Base b(two) is twice the length of base b( one).What are the lengths of the bases of the trapezoid? Triangle:- b=21 cm &h=6cm. Trapezoid:-h=6cm
Answer:
b2 = 14
b1 = 7
Step-by-step explanation:
Area_triangle = 1/2 b h
Area _trapezoid = (b1 + b2)h1/2
Since the areas of the two figures are the same, we get
1/2 b h = (b1 + b2)h1/2 multiply both sides by 2.
bh = (b1 + b2) h1
b=21
h = 6
2b1 = b2
216 = (b1 + 2b1)6 Divide by 6
21 = 3b1 Divide by 3
7 = b1
2b1 = b2
b2 = 14
Answer:
Answer:
b2 = 14
b1 = 7
Step-by-step explanation:
Area_triangle = 1/2 b h
Area _trapezoid = (b1 + b2)h1/2
Since the areas of the two figures are the same, we get
1/2 b h = (b1 + b2)h1/2 multiply both sides by 2.
bh = (b1 + b2) h1
b=21
h = 6
2b1 = b2
216 = (b1 + 2b1)6 Divide by 6
21 = 3b1 Divide by 3
7 = b1
2b1 = b2
b2 = 14
