Answer:
52 ft^2
Step-by-step explanation:
To find the area you just multiply 13 feet (length) by 4 feet (width). This gives you 52 feet squared because we are dealing with area and square feet.
La raíz de la cuadra de 81 es 9
Answer:
a=9 ( I think)
Step-by-step explanation:
we know that sqaure roots always equal to the base
(like 3^2 =9 or (root of 5)^2 equals to 5)
so I used "a" as a variable
so we must set it up at a^2= 9^3
of course, you must solve a, by sqaure rooting it
thus, leaving it
a= 9^(3/2)
but take my answer with a grain of salt ^^"
