1 answer:
Answer:
b = 4 inches and h = 14 inches
Step-by-step explanation:
Given that,
The area of a triangle, A = 28 sq inches
Height is twice less than 4 times the base.
H = 4b-2, b is base
We know that,
The area of a triangle is given by :
Base = 4 inches
Height = 4(4)-2
= 14 inches
Hence, this is the required solution.

Hi :) I'm guessing the shaded region is the region inside the rectangle but outside the circle.
To solve this problem, you need to find the area of the rectangle and area of the circle. Then subtract the circle's area from the rectangle's.
Area of a rectangle: length × width
The problem already tells you the area of the rectangle, because it says it is an 11 × 11 rectangle.
(11)(11) = 121
Area of rectangle: 121 units²
Area of a circle:
Plug in 5 for the radius r.
= 78.5
Area of circle: 78.5 units²
Now subtract 78.5 from 121.
121 - 78.5 = 42.5
The area of the shaded region is 42.5 units².
