Question

cm and the
14 cm.
Calculate the area of a trapezium in cm-, lengths of whose parallel sides (represented by
(iv) a = 8.5 cm, b = 3.4 cm, h = 6
nd distance between them (h) are :
(i) a = 45 cm, b = 32 cm, h = 11 cm
(ii) a = 4 dm, b = 8 cm, h = 1m
ii) a = 5 m, b = 50 cm, h = 50 dm​

Answer 1

Answer:

(i)423.5cm^2.

(ii)2400cm^2.

(iii)137500cm^2.

(iv)35.7cm^2.

Step-by-step explanation:

Area of trapezium=1/2×(a+b)×h.

(i)(45+32)×11/2=423.5cm^2.

(ii)(40+8)×100/2=2400cm^2.

(iii)(500+50)×500/2=137500cm^2.

(iv)(8.5+3.4)×6/2=35.7cm^2.
