Question

the area of a triangle is 14 square inches, and the triangles height is 7 inches. use the formula A = 1/2bh, where A is area, b is base, and h is height, to find the length of the base of the triangle.

○ 2 inches
○ 49 inches
○ 4 inches
○ 1 inch​

Answer 1

Answer:

A = BH x 1/2

Like they said, use the formula to find the base.

We plug in our given values, to find the base out.

A = BH x 1/2

14 = B(7) x 1/2

14= b7 x 1/2

Divide by 1/2 from both sides(basically multiplying by 2/1)

*2/1    *2/1

28 = b7(let's reverse this to be);

28 = 7b

/7     /7

4 = b
