hope it helps!!
Wa=0.5Wb, Ha=20, Hb is unkown
the area of rectangle a is : Wa*20
the area of rectangle b is : Wb*Hb
Rectangle a has 7 times the area of rectangle b: Wa*20=7*Wb*Hb
Replace Wa with 0.5Wb: 0.5Wb*20=7Wb*Hb => Hb=10/7
Answer:
Your answer would be the second option

Step-by-step explanation:
Answer:
8
Step-by-step explanation:
Area is 96, divide that by 4 triangles = Area is 24 per triangle
Area of a triangle = (0.5)(base)(height)
(0.5)(6)(x)=24
3x=24
x=8
The formula for that area would be A=1/2xbxh so you would do A=1/2x3.5x3 and that equals 5.25
