Question

if the area ofa trapezium is 28cm2 and one of its parallel sides is 6m find the other parallel side if altitude is 4cm

Answer 1

GIVEN AREA = 28CM²
ONE OF THE PARALLEL SIDE = 6M
HEIGHT = 4CM
LET OTHER PARALLEL SIDE BE X

SO , AREA OF TRAPEZIUM = 1/2×SUM OF PARALLEL SIDES × ALT.
28 = 1/2×(6+X) × 6
6+X = 2×28/6
6+X =28/3
2+X = 28
X = 28 -2
X = 26 ANS....

SO THE LENGTH OF OTHER PAR SIDE IS 26 CM.

So,
Hello Guys,

Answer is
AREA OF TRAPEZIUM = 28 cm²
A = 6 cm
B = ?
H = 4 cm

AREA OF TRAPEZIUM = ½×(a+b)×h
$28 \: cm \: = \frac{1}{2} \times (6 + b) \: \times 4 \\ 28 \: cm \: =(6 + b) \: \times 4 \\ \frac{28}{4} \: cm = 6 + b \\ 7 - 6 \: cm \: = b \\ 1 \: cm \: = b$

HOPE IT'S HELPS!!!!!!!
