Question 84840This question is from textbook Elementry and Entermeditate Algebra
: The area of a rectangle is 18 square meters. When the length is increased by 2 meters and the width by 3 meters the area becames 48 square meters. Find the dimensions of the smaller triangle.
Just by looking at this problem I can tell the answer is 6 meters and 3 meters. But I can not figure out how to set up the forula.
I tried (m+2)(m+3)=48
I then used FOIL then used the quadratic formula but it didn't work.
Can anybody help
