In the rectangular trapezoid ABCD AC is driven by a CD (see figure). Find the width of the trapezoid if AC = 3, AD = 5.

solution given:

let's see only in a right-angled triangle Δ ACD.

AC=3 units

AD=5 units

since Δ ACD is a right-angled triangle. It satisfies Pythagoras law

25=9+

=25-9=16

Now

Area of rectangle Δ ACD=

similarly,

since AB=CE=2.4 units

Δ ACE is a right-angled triangle. It satisfies Pythagoras law.

now

area of trapezoid=area ofΔACD+Area of ΔABC

=6+

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

it could be 1,3 and more others to create a cylinder.
