Hello.

What is the perimeter of a rectangle with width 10 inches and length 13 inches?

to find the perimeter of the rectangle we must add all its sides (4 sides)

side 1 = side 2= width=10 inches

side 3 = side 4 =lenght=13 inches

Perimeter=10+10+13+13 =46 inches

Answer

1.C 46 inches

2. What is the area of a triangle with base 19 inches in height 11 inches?

the area of a triangle is given by

A=(b*h)/(2)

where b is the base and h is the height

using our data

$A=(19*11)/(2) \\A=(209)/(2) \\Area=104.5 square inches$

the area is

2.B.104.5 square inches

3. What is the area of a circle with a radius of 15 inches, to the nearest tenth? Use 3.14 for pie.

the area of a circle is given by

$A=\pi \ r^(2)$

where r is the radius of the circle

using our data

$A=\pi \ r^(2)\\A=3.14\ *\ 15^(2)\\A=706.5$

the area is

3.D.706.5 square inches
