The diagram in the adjacent picture frame has outer dimension as 26 cm by 30 cm and the inner dimensions as 18 cm by 22 cm. Find the area of each section of the frame, if the width of each section is same.
Answers
Answer:
104 cm², 88 cm²
Step-by-step explanation:
∴ Area of figure(I) = Area of trapezium = (1/2)[a + b) * h
= (1/2)[30 + 22] * 4
= (1/2)[52] * 4
= 104 cm².
Also, Area of figure(II) = 104 cm².
∴ Area of figure(III) = Area of trapezium = (1/2)[a + b)] * h
= (1/2)[26 + 18] * 4
= (1/2) * 44 * 4
= 88 cm²
Also, Area of figure IV = 88 cm².
Therefore:
⇒ Area of figure I = Area of figure II = 104 cm².
⇒ Area of figure III = Area of figure IV = 88 cm².
