the length of the rectrangular field is twice its breadth ifvthe are of the field is 3200 square meters what is the cost of fencing the field at rs 40 per meter

Step-by-step explanation:

Area of a rectangle = Length x Breadth.

Area= L x B

We are told the length is twice the breadth.

You can write this as :

Length = 2 x Breadth

L = 2B

If you put that into the area formula at the beginning, we get:

Area = L x B

Area = 2B x B =

They also told us that the area of the field is 3200 square meters. So,

Area = = 3200

Divide both sides by 2

=

Now to solve for B we need to square root both sides.

= 40

So now we know the Breadth is 40meters

Remember earlier we said Length = 2 x Breadth

Cost of fencing the field = 2L + 2B

Cost of fencing the field = 2 x 80 + 2 x 40 = $240

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
