Answer 1

Answer:

Given- Figure

To find- Area of the figure

Solution- Divided the figure into 2

Traingle ABE and Square BCDE

Area of traingle= ½×b×h

h(height)= 23-15 = 8

½ × 15 × 8 = 60cm²

Area of square = side²

= 15×15 = 225cm²

Area of total figure = 225+60 cm² = 285cm²

Answer - Hence, 285cm² is the area of ABCDE
