Answer.....15ft by 12ft
Explanation:
Area = Length × Width
180 = LW....make W the subject of formula
;W = 180/L
Perimeter = 2L + 2W
54 = 2L + 2(180/L)...sub W with the formula above...
then simplify the equation and obtain...
2L^2 - 27L + 180 = 0....then solve using the quadratic formula....then obtain..
;L = 15ft....after obtaining L = 15...then substitute into the W = 180/L equation...
where W = 180/15 = 12ft
there you have...Length = 15ft and Width = 12ft
The equation that calculates the unknown side length, M of the Chocolate Shoppe rectangular logo is A = 3.1H
<h3>How to determine the equation?</h3>
The parameters in the question are:
- Logo: Rectangle
- Height, H = 3 1/10 feet
Represent the area of the logo with A, and L represents the unknown side
The area (A) of the rectangle is calculated using:
A = H * L
Substitute 3 1/10 for H
A = 3 1/10 * H
Express the fraction as decimal
A = 3.1H
Hence, the equation that could be used to determine the unknown side length, M of the logo is A = 3.1H

How to find area of a parallelogram?</h3>
A parallelogram is simply a quadrilateral with two pairs of parallel sides.
The area of a parallelogram is expressed as;
A = base × height
Given the data in the diagram;
- Height of the parallelogram = 13cm
- Base of the parallelogram = 20cm
- Area of the parallelogram = ?
Plug the given values into the equation above and solve for A.
A = base × height
A = 20cm × 13cm
A = 260cm²
The area of the parallelogram with a height of 13cm and base 20cm is 260cm².
