the diagram of the adjacent picture frame has outer dimensions 26cm x 30cm and i ner dimensions 18cm x 22cm. 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.
