first we'll find area of trapezium.

area of trapezium = 1/2×height×(sum of parellel sides of the trapezium)

area of trapezium =1/2×4×(13+24)

area of trapezium =1/2×4×37

area pf trapezium = 74in²

now area of rectangle.

area of rectangle = length ×width

area of rectangle= 24in×7in

area of rectangle =168 in²

area of the figure= 74in²+168in²

area of figure=242in²
