Question

Line x + y = 5 intersect the x-axis and y-axis at F and G respectively and line x + y = –5 intersect the x-axis and y-axis at H and E respectively. Also, lines x = y = –5 intersect at A, lines x = –y = 5 intersect at B, lines x = y = 5 intersect at C and lines x = –y = –5 intersect at D. The difference of areas of squares ABCD and EFGH (in square units) is

रेखा x + y = 5, x-अक्ष व y-अक्ष को क्रमशः F तथा G पर प्रतिच्छेद करती है तथा रेखा x + y = –5, x-अक्ष व y-अक्ष को क्रमशः H तथा E पर प्रतिच्छेद करती है। इसी प्रकार, रेखाएँ x = y = –5, A पर प्रतिच्छेद करती है, रेखाएँ x = –y = 5, B पर प्रतिच्छेद करती है, रेखाएँ x = y = 5, C पर प्रतिच्छेद करती है तथा रेखाएँ x = –y = –5, D पर प्रतिच्छेद करती है। तब वर्ग ABCD तथा EFGH के क्षेत्रफलों (वर्ग इकाई में) का अन्तर है
