If base of parellogram is 12 cm lenght is 8cm and prependecular diatance beetween two bases is 7cm find its area and perimeter

84 cm^2

10 cm

Step-by-step explanation:

A parallelogram is  quadrilateral that has two pairs of parallel sides. The opposite sides  equal in length

Area = base x height

12 x 7 = 84 cm^2

Perimeter = 1/2 x ( base + length)

1/2 x (12 + 8) = 10 cm

step-by-step explanation:

mark brainliest!

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
