How do you find the area of the rectangle given the side of it is 3-√10 the bottom is 4√10?

Answer 1

120 square units

The area of a rectangle is A = lb , where l , is the length and b , the breadth.

here #l=4sqrt10" and " b=3sqrt10#
#rArrA=4sqrt10xx3sqrt10=4xx3xxsqrt10xxsqrt10#
Note: in general #sqrtaxxsqrta=a#
#rArrsqrt10xxsqrt10=10#
#rArrA=4xx3xx10=12xx10=120" square units"#

Answer 2

To find the area of a rectangle with sides ( 3 - \sqrt{10} ) and ( 4\sqrt{10} ), you multiply the length by the width:

[ \text{Area} = \text{length} \times \text{width} = (3 - \sqrt{10}) \times 4\sqrt{10} ]

[ \text{Area} = 12\sqrt{10} - 4\sqrt{10}\sqrt{10} = 12\sqrt{10} - 4 \times 10 = 12\sqrt{10} - 40 ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
