Answer:
So use pythogoras theorem
a^2=c^2-b^2
a^2 = 20^2-12^2
a^2= 256
a= square root of 256
length is 16 ft
area = l x w
= 16 x 12
Area is 192 square feet
Step-by-step explanation:
Answer:
The length = 192 feet squared
The diagonal = 16 feet
Step-by-step explanation:
Over here, we can use the Pythagorean theorem which states that in a right triangle, a^2+b^2=c^2
The width measures 12 and the diagonal measures 20, so we have a and c, so 144+b^2=400 which simplifies to b^2=256. The square root of 256 is 16 so that's our length
Then we just plug in the formula to find the area of a rectangle which is l*w, so 12*16=192
