a photograph is 5.5 in. long and 3.2 in. wide. it must be enlarged so that both dimensions are 1.8 times greater. how long will the photograph be then?
15.66
To find the new length of the photograph after it is enlarged, we need to multiply its original length by the given scale factor of 1.8.
Step 1: Multiply the original length by the scale factor:
5.5 in. * 1.8 = 9.9 in.
Therefore, the photograph will be 9.9 inches long after it is enlarged.
To determine the length of the photograph after being enlarged, we need to multiply the original length by the enlargement factor.
The enlargement factor is defined as 1.8 times greater. So to find the new length, you can multiply the original length by 1.8.
Original length = 5.5 inches
Enlargement factor = 1.8
Length after enlargement = Original length * Enlargement factor
= 5.5 inches * 1.8
= 9.9 inches
Therefore, the length of the photograph after being enlarged will be 9.9 inches.
1.8 * 5.5 =
1.8 * 3.2 =
