5^2=3^2+4^2 ⇒ the triangle has an ungle =90 °

The area is 3*4/2=6 cm^2

There is no slope, it’s undefined. you get this by doing 9-(-4)/-4-(-4). this comes out to 13/0, and anything over zero is undefined. hope this helped

Please help me it is an easy question

Ugo [173]

Answer:

200 yd²

Step-by-step explanation:

A = 17 yd

B = 15 yd

C = 2 yd

D = 8 yd

b) Area of rectangle = length * width

$\sf Area \ of \ 2 \ triangle = 2* \dfrac{1}{2}* base * height = base* height\\\\$

Area of right triangular prism = Areas of two triangle + area of the upper rectangle + area of middle rectangle + area of below rectangle

= 8 * 15 + 17 * 2 + 15 *2 + 8*2

= 120 + 34 + 30 + 16

= 200 yd²
