Dora leaned a 94 foot ladder against the side of a building. The base of the ladder is 9 feet from the base of the building. The top of the ladder is 13 feet from the top of the building. How tall, to the nearest tenth of a foot is the building?

126.6 ft

Step-by-step explanation:

I've attached a picture.  Look at the right triangle.  A side is missing.  Use the Pythagorean Theorem to find it.

(leg)^2 + (leg)^2 = (hypotenuse)^2

The ladder touches the wall at a height of 93.6 ft.  Now add the 13 "extra" feet from the top of the ladder to the top of the building.

The building is 126.6 ft tall.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
