Leroy's backyard is a rectangle that is three times as long as it is wide. what is the perimeter and the area of the yard? first draw a diagram to you solve the problem. let a be the width of leroy's yard. the perimeter is a+3a+a+3a or 8a. the area is l×w; so the backyard area is a×3a or 3a^2. suppose you know the area of the yard 7,500 square feet how can you find the value of a?

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
