Ill give BRAINLIEST if right! pls help!

Step-by-step explanation:

Drop a height directly through the middle of the triangle, intersecting the base at a 90 degree angle. We form two right triangles and can use the Pythagorean theorem to solve for the hypotenuse.

The Pythagorean theorem states that for any right triangle, the following is true:

, where and are two legs of the triangle and is the hypotenuse.

Therefore, we have the following equation (using the graph to measure the length of the two legs):

The other "tilted" side must be the same length. The base of the triangle can be measured using the graph - 10 units.

Therefore, the perimeter is

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
