Answer:

Choice B

Step-by-step explanation:

We have to find area of triangle.

We have given the base of triangle and altitude of triangle.

From question statement,we observe that

base=b= 10 inches and height=h=altitude= 4 inches

The area of triangle is half of base times the height of triangle.

Area= 1/2×base×height

By putting the values of base and height in above formula,we get

Area = 1/2×10×14

Area = 70 in².

hence, choice B is correct answer.

Answer:

The correct option is B.

Step-by-step explanation:

The area of triangle is

$A=\frac{1}{2}\times b\times h$

Where, b is the base of the triangle and h is the height of the triangle.

It is given that the base of the triangle is 10 inch and the height of the triangle is 14 inch.

The area of given triangle is

$A=\frac{1}{2}\times 10\times 14$

$A=10\times 7$

$A=70$

Therefore the area of triangle is 70 square inch and the option B is correct.
