Cube surface area = side^2 * 6
cube surface area = 2.3^2 * 6
cube surface area = 31.74 cm^2
AB = √(-4)² + (-3)²
AB = √ 16 + 9
AB = √ 25
AB = 5
AD = 4 ; DC = 4 ; BC = 7
Perimeter = 5 + 4 + 4 + 7 = 20 units
6 feet and 3 feet
6x3=18 for the area
and 6+6+3+3= 18 for the perimeter
Two shaped are merged so
One is square and the other is trapezoid so,
AREA OF SQUARE=4*4
=16
AREA OF TRAPEZOID=(2+4)x4/2
So,rhe answer will be
12+16=28
HOPE IT IS HELPFUL
