Suppose you know the base of a rectangle has a length of 12 inches and a diagonal has a lenght of 13 inches. find the area of the rectangle

We are given

length=l=12inches

diagonal =d=13inches

Let's assume

width=w

so, firstly we need to find width

we know that length , width and diagonal form right angled triangle

so, we can use Pythagoras theorem

now, we can plug values

now, we can find area of rectangle

Area = length*width

now, we can plug values

correct answer:

i^31 = -i

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
