Pls, can someone answer this, Explain, using words and numbers, how to subtract 7x - ( 6x + 13). Remember to include the solution to the expression with your explanation. *

What is the area of a triangle?

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

The space occupied by any two-dimensional figure in a plane is called the area. The two-dimensional space occupied by the triangle is called the area of the triangle.

Given that right triangles, MNP and QRS are congruent. Right triangles M N P and Q R S are shown. The length of side Q S is 8 meters. The length of M N is 17 meters and the length of P N is 15 meters.

The area of the triangle is calculated as,

Area = (1/2) x PN x QS

Area = (1/2) x 8 x 15

Area = 4 x 15

Area = 60 square meters

Therefore, the area of the triangle will be equal to 60 square meters. The correct option is B.
