if the width of a rectangular exercise mat was 6 meters and you add 2 more meters which would be 8 meters. what is another name for the shape of this exercise mat? explain how you know
I will assume that the dimensions of the rectangle are
Length is 8 meters
width is 6 meters
so
the rectangle is 6 m x 8 m
If you add 2 meters to the width
we have
W=6+2=8 meters
The figure is now a square
because the length is equal to the width
Part 2
melissa has enough paint to cover an area of 250 square feet. she wants to paint to walls. the rectangular wall is 9ft high and 20ft wide. the square wall has a height of 9 feet. does melissa have enough paint to cover the area of both walls? can you show me how to work this?
step 1
Find out the area of both walls
rectangular wall
A=(9)*(20) ------> A=180 ft2
Square wall
A=(9)^2 ------> A=81 ft2
Add the areas
A=180+81 =261 ft2
step 2
Compare the total area with the 250 square feet
261 ft2 > 250 ft2
that means
Melissa has not have enough paint to paints the walls
