Question

find the area of a rhombus whose diagonals are of length 20cm and 4.5cm​

Answer 1

Answer:

45cm² is the answer

Answer 2

Answer:

area of rhombus by using diagonals

AREA= p q /2 , where p and q are value of diagonals

or, 20*4.5/2

or, 90/2

or, 45 cm

or, area =45 CM sq.

Step-by-step explanation:

2nd question solve '

: area of trapezium field= 1/2 *(sum of parallel sides) *height

let one parallel side as S and other be 20 cm . and height is 15 cm

or, 480 cm sq. = 1/2 (20 +S) * 15

or, 480/15= 10 + S/2

or, 32 - 10 = S /2

or , 22*2 = S

or,44 = S = another side of trapezium
