Un rectángulo tiene 36 cm de perímetro y 80m2 (a la 2) de área .¿cuales son las dimensiones del rectángulo

Let's assume

length of rectangle is L

width of rectangle is W

we can find perimeter

perimeter =2L+2W

now, we are given

perimeter =36

so, we get

now, we can solve for L

now, we can find area

we are given area =80

so, we get equation as

now, we can plug back L

now, we can solve for W

now, we can find length

At W=8:

At W=10:

So, dimensions of rectangle are

Length of rectangle is 10cm

Width of rectangle is 8cm

OR

Length of rectangle is 8cm

Width of rectangle is 10cm ..............Answer

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
