Question

An art class is painting a rectangular mural for a community festival. The students planned the mural with a diagram that is 80 in. long and 16 in. high. The mural is 48 in. high. What is its length?

Answer 1

80/16 = x/48
80*48/16 = x
x = 240

the mural will be 240in in length

Answer 2

240 inches

Explanation:

Given : The students planned the mural with a diagram that is 80 in. long and 16 in. high.

The mural is 48 in. high.

To Find: What is its length?

Solution:

The students planned the mural with a diagram that is 80 in. long and 16 in. high.

Actual height = 48 inches

To calculate scale

So, 16 inch = 48 inch

So, 1 inch =
`(48)/(16)` inches

So, 1 inch = 3 inches

Length of room = 80 inches

Actual length of room =
`80* 3`

=
`240`

So, its length is 240 inches.

Hence the actual length of room is 240 inches.
