A rectangle has an area of 75.2m2. One of the sides is 0.8m in length.
Work out the perimeter of the rectangle.

189.6m

Step-by-step explanation:

Area of reactangle= side₁ ×side₂

Let the other side of the rectangle be x meters.

Area of rectangle= 75.2m²

0.8x= 75.2

x= 75.2 ÷0.8

x= 94

Perimeter of rectangle

= 2(side₁ +side₂)

= 2(0.8 +94)

= 189.6 m

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
