find area given question
Answers
Answer:
1 )
area of triangle = 1/2 × 12×30
= 180 cm²
area of trapezium = 1/2 h(a+b)
= 1/2 × 15 ( 30 + 24 )
= 1/2 × 15 × 44
= 330 cm²
total area = 330 + 180
= 510 cm²
2 ) Since it is a regular hexagon , we split it into 2 triangles and 1 rectangle
The area if both riangles are same so we will find the area of one of them and multiply with 2
area of triangle = 1/2 × 40 × 15
= 300 cm²
area of 2 triangles = 600 cm²
area of rectangle = 28 × 40
= 1120 cm²
total area = 1120 + 600
= 1720 cm²

Answer:
Step-by-step explanation:
1.
area of BCDE
= 1/2(CD+BE)15
= 1/2(24+30)15
= 1/2(54)(15)
= 355 cm2
area of ABE
1/2(b)(h)
= 1/2(30)(12)
= 180 cm2
therefore total area is 535 cm2.
2.
area of PRTU
= l*b
= 40*28
= 1120 cm2
area of PQU = area of RST
= 1/2*b*h
= 1/2*40*15
= 300 cm2
therefore the total area is 1420 cm2.
