House with Door
House with Door: a composite plane figure made of a square with side 6.2 cm, joined with a triangle with base 6.2 cm and height 3.4 cm, minus a rectangle 2 × 3 cm. It is a classic primary school geometry problem (“Frames & Cutouts”). The net area is 42.98 cm² and the total perimeter is 33.8 cm.

How to find the area
Area formula: A = l² + ½·l·h_t − b_p·h_p
Split the figure into basic shapes, find each area, add the joined parts and subtract the cut-outs: A = 38.44 + 10.54 − 6 = 42.98 cm².
