Answer:

Suzanne needs 40\ ft of fencing

Step-by-step explanation:

Step 1

we know that

The area of a square is equal to

A=b^{2}

where

b is the length side of the square

In this problem we have

A=100\ ft^{2}

substitute and solve for b

100=b^{2}

square root both sides

1b=10\ ft

Step 2

Find the perimeter of the square garden

The perimeter of the square is equal to

P=4b

we have

1b=10\ ft

substitute

P=4(10)=40\ ft

The squarefoot of 100 = 10ft 
and there are 4 sides to a square so 10+10+10+10=40ft of fencing

Find the perimeter of a rectangle with a length of
Luba_88 [7]

Answer:

P = 8\sqrt{2} + 10 + 2\sqrt{6}

Can only be simplified through calculator using decimal equivalents.

Step-by-step explanation:

The perimeter of a rectangle is the formula P=2l+2w. Here l=4\sqrt{2} and w=5+\sqrt{6}. So the perimeter is:

P= 2l+2w\\P = 2(4\sqrt{2} ) + 2(5+\sqrt{6} )\\P = 8\sqrt{2} + 10 + 2\sqrt{6}

marysya [2.9K]
C:x(t)=e^t\sin10t;\,y(t)=e^t\cos10t;\,0\le t\le2

\displaystyle\int_0^2\sqrt{x'(t)^2+y'(t)^2}\,\mathrm dt
\displaystyle=\int_0^2\sqrt{(e^t\sin10t+10e^t\cos10t)^2+(e^t\cos10t-10e^t\sin10t)^2}\,\mathrm dt
\displaystyle=\int_0^2e^t\sqrt{\sin^210t+20\sin10t\cos10t+100\cos^210t+\cos^210t-20\sin10t\cos10t+100\sin^210t}\,\mathrm dt
=\displaystyle\int_0^2e^t\sqrt{1+100}\,\mathrm dt
=\displaystyle\sqrt{101}(e^2-1)
