Start naming variables.Hey, i have a problem and i need help to solve this. I need to do a system for this.
"The perimeter of a rectangular shaped lot is 30m. Knowing that the area of the lot is 56m2, do you know its size?"
Can someone help me, i need some help.
INTEGERS that multiply to 56 are 56x1, 28x2, 14x 4, 7x8.Consider one side of the rectangle to be x and the other y
therefore 2x+2y=30
and xy (multiply x by y) = 56
Numbers that multiply to 56 are 28 x 2 but 28+28+2+2 is more than 30
the other option is 8 x 7, 8+8+7+7 =30
so the side lengths of the rectangle (x & y) are 8 and 7
