Find the area of a rectangle with a perimeter of 12 meters and a base of 4 meters
stepladder [879]
Considering the perimeter (P)
p = 2 \times b + 2 \times h
where b is the base and h is the height, then
12 = 2 \times 4 \times 2 \times h \\  \\ h =  \frac{12 - (2 \times 4)}{2}  \\  \\ h = 2
Being the area (A)
a = b \times h \\  \\ a = 4 \times 2 \\  \\ a = 8 {m}^{2}

What is the answer to this
arlik [135]

S\frac{O}{H} C\frac{A}{H} T\frac{O}{A} or Sin\frac{Opposite}{Hypotenuse}Cos\frac{Adjacent}{Hypotenuse} Tan\frac{Opposite}{Adjacent}


At the point/angle E:

- the adjacent side(side <u>next to</u> the point/angle) is ED

- the opposite side(side of the triangle <u>across</u> from the point/angle) is DF

- the hypotenuse (the<u> longest side</u> of the triangle) is EF.


sin ∠E = \frac{opposite}{hypotenuse}

sin ∠E = \frac{6}{10} = \frac{3}{5} (simplified)
