Brainiest to whoever right.

The problems listed are all the formulas for 2d figures:

Area of a Triangle: 1/2 B*H

Area of a Square: S^2

Area of a Rectangle: l*w

Perimeter of a Square: 4s

Perimeter of a Triangle: a+b+c

Perimeter of a Rectangle: 2l+2w

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
